| In the recent years, eyetracking devices have made tremendous improvements wrt. their accuracy, the comfort of use and also the costs. These trends open up new possibilities apart from their classical application domains in e.g. customer analysis where only little number of devices are used for one-time experiments. The DFKI has investigated to what degree eye trackers can improve our daily lives, assuming that with raising sales figures these devices might soon become affordable to everyone. Under the label “Text 2.0” we developed a framework that observes the user when reading text on a computer screen using a desktop eye tracker. It not only recognizes which textline or word a user currently looks at, but also if he is skimming over a text, or getting stuck at some word. These mechanisms have led to a series of applications and proactive services ranging from entertainment to education. In parallel, we worked with mobile eye trackers which permit services apart from monitor screens. By analyzing the provided scene image together with eye fixations and optional movement sensors we built several prototypes that anticipate when the user shows interest to some object. Sample applications are the “MuseumGuide2.0” or an automatic “Visual Diary”. |
